A method of forming a macrocyclic musk compound comprising the steps of:- i) cross-metathesizing a first olefin and a second olefin in the presence of a homogeneous transition metal catalyst comprising an alkylidene ligand, to form a statistical mixture of a hetero-dimer intermediate of said first and second terminal olefin, and homo-dimers ii) separating the hetero-dimer from the statistical mixture of hetero-and homo- dimers iii) and cyclizing the hetero-dimer intermediate to form the macrocyclic musk compound.
形成大环麝香化合物的方法包括以下步骤:i)在存在包含烷基亚烯配体的均相过渡金属催化剂的情况下,交叉烯烃化第一烯烃和第二烯烃,形成所述第一和第二末端烯烃的异二聚体中间体的统计混合物,以及同二聚体;ii)将异二聚体从异二聚体和同二聚体的统计混合物中分离出来;iii)并将异二聚体中间体环化,形成大环麝香化合物。
